Thanks, that made a difference. Appears to be suspending to RAM -- hard drive spins down, crescent-moon indicator lights up, screen goes black...but then the backlight comes back on while remaining in sleep mode. Closing and opening the lid brings it back to life promptly with no stripes on the screen, everything is working fine. I just repeated this reliably about 10 times in a row. Now if I could figure out how to keep the backlight from coming back on immediately after the suspend. Also wondering how much I'd be giving up by forgoing DRM in my case with this "mobility radeon 7000". Rebooted, then suspended to the frozen screen with vertical stripes, tried the suggested `bo re` ... but no, that screen is frozen solid. Regards, John -- John Magolske http://B79.net/contact
